Since the experimental costs are increasing, optimal experimental design has been widely used nowadays for a more efficient process. Using some algorithms to generate optimal designs for different specific models is more effective than finding analytical results for complicated models. Therefore, we use particle swarm optimization (PSO) to generate the best result for model selected by users. Here we built up a web-based interactive platform for practitioners, which contains different types of optimal designs for different experimental problems, and the users don't need any programming skills but can operate easily. We will demonstrate the usage of PSO in solving different types of optimal designs through the website.
